'Jamea Kantor ATTORNEYS Reissued Dec. 3, 1935 UNITED STATES Re. 19,777 v PATENT OFFICE SIRUP VALVE FOR BOTTLE FILLERS James Kantor, Chicago, Ill., assignor to The Liquid Carbonic Corporation, Chicago, 111., a corporation of Delaware 17 Claims.

My invention relates to improvements in apparatus for delivering sirup for bottle filling machines such, for instance, as bottle machines for bottling carbonated beverages. Heretofore such structures have comprised a sirup receptacle which is reciprocable to be moved down upon and up away from the bottle. This receptacle has been supported by a reciprocating cylinder and in order to insure the discharge of the sirup from the receptacle, there has been provided a plunger. This plunger, when the receptacle comes to rest on the top of the bottle, continues its downward vmovement in the receptacle insuring the discharge of the sirup from the receptacle. Heretofore this plunger has been raised in the receptacle by the incoming sirup which is discharged into the receptacle after the charge therein has been delivered to the bottle. Some sirups are heavier or thicker than others and as a result require greater weight in the plunger to force the same out of the receptacle. However, heretofore the weight of this plunger has been limited due to the fact that the entire weight tending to f rce the plunger downwardly under inertia had to e raised by the incoming sirup and in order to get sufflcient force, the sirup from the storage tank had to have a considerable head. It has been necessary, therefore, to place the storage receptacle at a considerable height above the machine and it has been found in some instances that this is impracticable due to the limit of the ceiling height of the bottling factory.

It is one of the objects of my present invention to provide a sirup delivery device wherein the weight of the plunger may be increased during its discharge stroke, while the plunger will be relieved of this increased weight during the inflow of the sirup, thereby providing a relatively heavy plunger for discharge purposes and a relatively light plunger which will require a minimum head in the sirup storage tank for raising the plunger during the inflow into the sirup.

For the purpose of disclosing my invention, I have illustrated one embodiment thereof in which the figure is a longitudinal section of a sirup filling apparatus embodying my invention.

In the embodiment of the invention illustrated, I provide a cylinder support. I which is adapted to be secured to a reciprocating part of the machine and is adapted to be vertically reciprocated. Within the support is mounted the sirup receptacle 2, which may also be of cylindrical shape. A compression spring 3 is interposed between the parts I and 2, the upper end of the spring engaging thetop l or the cylinder I and the lower end engaging an annular flange 5 at the lower end of the receptacle 2. The relative movement in one direction between the cylinder I and the receptacle 2, under the influence of the spring 3, is

limited by adjustable stop nuts 6 at the top of the 5 guide rods I. These guide rods project through the top of the cylinder l and at their lower ends are screw threaded into bosses on the sides of the receptacle 2 providing for further adjustment of the stop nuts. nuts 6, through their threaded engagement with the rod I, or by adjusting the rod I through its threaded engagement with the cylinder 8, the nuts 6 provide adjustable stops for the cylinder 8 and its position relative to the support I may be 15 thereby modified. The bottom of the receptacle 2 is provided with a discharge and inlet port 9, which discharges through an opening Ill into a spout I I having at its lower end a mouth piece I2 adapted, when the structure is lowered, to engage 20 the top of the bottle. This mouth piece is provided with a washer I3. The spout has a slight movement relative to the bottom of the receptacle 2 and is biased toward the outermost limit of its movement by a coiled spring I4 interposed be- 25 tween the bottom of the receptacle and the mouth piece I2. The flow of sirup from the receptacle 2 and through the port 9 into the mouth piece II and the flow of sirup from the supply pipe I5 through the port I6 and into the receptacle is con- 3 trolled by a valve H, which when the receptacle is in its raised position, closes the spout II and allows the flow of sirup from the port It into the receptacle 2. When, however, the receptacle is in its lowermost position and in contact with 35 the bottle, the valve is in its raised position shutting off the flow of sirup from the port I6 and opening access to the spout I I. 7

Operating within the receptacle 2 is a plunger I8, the weight of which may be increased by an annular removable weight I9, and which is adapted to be engaged by a threaded stem 20. This stem is threaded into the lower end of an elongated cylindrical nut member 2| projecting through a top opening in the cylinder and pro- 45 vided at its upper end with an annular flange 22 by which it is supported from the top of the cylinder. This flange is provided with openings through which the guide rods 1 pass. The stem is screw threaded in this nut which permits of 50 the adjustment of the plunger I8 to vary the height to which the plunger may be moved in the receptacle 2 and after having been adjusted the stem may be locked in its adjusted position by means of a locking screw 23.

It is obvious that by adjusting the 10 In operation, when the bottle has been placed beneath the mouth piece I2, the cylinder I moves downwardly carrying with it the receptacle 2. Due to the spring 3, however, after the mouth piece I2 has come in contact with the neck of the bottle, to thereby check the downward movement of the receptacle 2, the cylinder I can continue in its downward movement. This continued downward movement leaves the weight of the stem 28 and nut 2| unsupported and this weight, plus the weight of the plunger I8 will move downwardly under the influence of gravity thereby forcing the sirup in the chamber I out through the spout II and into the bottle, the valve I! having been raised when the mouth piece comes in contact with the neck of the bottle. As soon as the plunger reaches the lowermost limit of its downward movement, the bottom of the receptacle acting as a stop for the plunger to prevent its contacting with the valve, the cylinder I commences its upward stroke, its top engaging the flange 22, first raising the stem 20 and nut 2| and the flange then engaging the stop nut 6, thereby raising the receptacle 2. This permits the valve 1 to drop back on its seat over the mouth piece II closing the discharge opening of the receptacle and opening the inlet of the receptacle so that the sirup may flow from the supply pipe I5 into the receptacle. The inflow of the sirup raises the plunger I8, the stem. 20 having been raised out of its path, until the plunger I8 comes in contact with the bottom of the stem. This limits the upward movement of the plunger and stops the inflow of sirup.

It will therefore be noted that during the discharge movement of the plunger the weight thereof is materially increased. by the weight of the stem 28 and the nut 2|, but that during the fllling of the receptacle the weight of the stem and nut has been removed from the plunger I8 so that it will offer comparatively slight resistance to the inflow of the sirup.
